Asia's second and India's longest railroad 'Bogibeel Bridge' is 4.95 km-long only fully welded bridge and for the first time European codes and welding standards were adhered to and it has a life of about 120 years.

The Bogibeel Bridge connects the southern bank of the Brahmaputra River in Assam’s Dibrugarh district with Silapathar in Dhemaji district, bordering Arunachal Pradesh. This Double-Track and three-lane Road Bridge will be the lifeline of the north-eastern part of India

The Bogibeel Bridge is constructed at a cost of Rs 5,900 crore and it is part of infrastructure projects planned to improve logistics along the border in Arunachal Pradesh which includes the construction of a trans-Arunachal highway on the Brahmaputra’s north bank, and new road and rail links over the river and its major tributaries.

The Bogibeel Bridge is referred to as “Lifeline of Assam”, It is an asset for the entire north-eastern region. The benefits of the bridge include:

It reduces travel time from Assam to Arunachal Pradesh to four hours and will eliminate a detour of over 170 km via Tinsukia.

It also reduces the train travel time between Delhi and Dibrugarh by about three hours.

The bridge will also play an important role in defence of the country by facilitating ease of mobility to the India-China border in Arunachal Pradesh and also the three road lanes of the bridge can act as three landing strips for the Air Force.

The foundation stone for the Bogibeel Bridge was laid by former Prime Minister HD Deve Gowda on January 22, 1997. The work had begun on 21st April 2002, under the Atal Bihari Vajpayee led government. It is now inaugurated on the birth anniversary of the former Prime Minister Atal Bihari Vajpayee.
